Repast Simphony is a tightly integrated, richly interactive, cross platform Java-based modeling system that runs under Microsoft Windows, Apple Mac OS X, and Linux. It supports the development of extremely flexible models of interacting agents for use on workstations and small computing clusters.

Repast Simphony models can be developed in several different forms including the ReLogo dialect of Logo, point-and-click flowcharts, Groovy, or Java, all of which can be fluidly interleaved. NetLogo models can also be imported.
